CUTTING UNITS

Marcelling
NOTE: One cutting unit width shown. Arrow indicates
direction of travel.
Marcelling is a wave-like cut appearance similar to
washboarding but with a uniform cutting height and
smaller wave tip-to-tip distance. In most cases, the wave
tip-to-tip distance is 2 in. (5 cm) or less. Color variation
(light-to-dark) may also be noticed. This condition is
usually caused by an incorrect frequency-of-clip.
Probable Cause Remedy
Incorrect frequency-of-clip. Check and adjust frequency-of-clip. Frequency-of-clip must be
equal to or less than height-of-cut.
Verify proper reel is being used for the correct application and
change if necessary. May need more blades.
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
HOC (height-of-cut) setting is too low for the machine’s
capability.
Confirm proper HOC range for reel/bedknife combination.
Reel speed is too low. Check/set reel speed rpm or repair/replace reel drive motor as
necessary.
